The CC1120 955MHz EM reference design contains schematics and layout files for the CC1120EM 955MHz evaluation module. The reference design demonstrates good techniques for CC1120 decoupling and RF layout. For optimum RF performance, these parts should be copied accurately. This is a 4-layer reference design with a discrete balun and an SMA antenna connector designed for a single ended 50 ohm antenna. The RF section has been designed and characterized for operation in the 955 MHz frequency band.
